6 Claims.

'I'his invention relates to' window operators for pulling the window,and further, which holds the window in any desired position between orat its limits of movement without resorting to supplementary holdingdevices. It is another ob- .lect of this invention to provide anoperator of the above nature which takes up a minimum amount of room inthe window opening, and yet which is suiiiciently extendable tocompletely open the Window.

Other objects will be in part apparent and in part pointed outhereinafter.

The invention accordingly consists in the features of construction,combinations of elements, and arrangements of parts, as will beexemplified in the structure to be hereinafter described, and the scopeof the application of which will be indicated in the following claims.

Figure 12 is a sectional elevation taken the une lzflz of Figure 9.

Similar reference characters refer to similar along parts throughout thevarious Views Aof the drawings.

Referring iirst to Figure 1 of the drawings, a

Vbase plate l5, which is adapted to be secured to the sill of the windowopening has mounted'there on a bottom bar I6 of the window frame, andthese two parts have secured thereto one element il of a hinge generallyindicated at i8. Hinge 58 as shown is of the type described in detail inour United States Letters Patent No. 1,955,653, and further is of thetype provided for a -projected easement window. Hinge I3 accordinglyincludes a movable element IS to which is secured the bottom sash bar Zof the window sash.v

Also secured to base plate l5 is an operator generally indicated at 2l,which includes relatively extensible members generally 'indicated at22,V ywhich are attached to sash bar 2li. Operator 2l also includes amanually rotatable crank or the like 23 which upon operation swings thewindow sash.

Operator 2| comprises a base 24 secured by screws 25 to base plate l5. Aweb 26 (Figure 2) extends upwardly from base 24 and is joined to anotherweb 2l also extending upwardly from base 2li. 'I'hese two webs support ajournal or housing 28 whose axis extends diagonally with respect tol web21 and base`24 of the operator.

Housing 28 rotatably carries a shaft or the like (not shown) to one endof which is attached crank 23 (Figure 1) and to the other end of whichis attached one element or fork of a universal joint, the other element30' of which is secured to the inner end of the relatively extensiblemembers 22. l

Members 22 include a tubular interiorly threaded member 3l whichthreadably receives a screw 32 the outer or exposed end of which ispivoted at 33 to a lug 361A or the like secured to ksash bar 23. It willnow appear that upon operation of crank 23, tubular element 3| will berotated by reason of its connection to the crank through the universaljoint elements 29 and', and in accordance with the direction of rotationof element 3|, screw 32 is extended or projected from` the tube or isdrawn thereinto, as the screw is constrained against rotation by reasonof its attach-l ment to lug'34. Thus, the only possible movement ofscrew 32 with respect to tube 3l is axial, although both elements arepivotable with respect to operator 2l and accordingly base plate l5.

Assuming that element 3| rotates in the direction to draw screw 32 intoelement 3l, sash bar 20 is swung clockwise until it reaches the dottedline position shown in Figure l. Reverse rotation 3| and 32,supplementary sash locking devices are unnecessary as the sash iseffectively locked in any desired position and furthermore rattling ofthe sash in its opened, closed, or in any inter mediate position isprecluded as there is little or no play in the window operating elements2| and 22 or in the hinge i8. Also, by reason of the telescopingrelationship of elements 3| and 32, these elements occupy but a limitedamount of space in the window opening, and aside from their efficiencyin operation, are both sturdy and neat in appearance.

Referring now to the modied form of operator generally indicated at 35in Figure 3, a base 36 carries a substantially crescent-shaped or U-shaped support 31 to which is secured in any suitable manner a curvedwall portion 38 (Figure on the top of which is mounted a cover plate 39.A web 49 (Figure 3) is secured to support 31, wall 36 and top 39, andthrough this web and top extends a journal 4| or the like (Figures 3 and4) whose axis is diagonal to the plane of the web and to the plane ofbottom or base 36. As shown in Figure 5, journal 4| opens into theenclosure between top 39 and base 36 (Figure 3) and rotatably carries asplit shaft generally indi- I cated at 42 in Figure 4. Shaft 42comprises a pair of elements 43 and 44 joined by a key 45 or the like.Shaft element 43 includes a reduced portion 46 which extends into theshank of a crank 6|), by which the operator is manually 1 operated.Shaft element 44 has connected thereto one end 41a of a exible cable 41which extends into the enclosure between base 36 and top 39 of theoperator.

Base 36 (Figure 4) has a circular groove 48 and top 39 has a similarregistering groove 49, in which a cylindrical housing 50 is rotatablymounted. That portion of housing 59 (Figure 5) which is exposed, i. e.which lies outside of curved wall 38, is formed with a tubularprojection 5| adapted to journal a rotatable stud 52 having a centralcore 53 in which the other end 41h of flexible cable 41 is secured as bya pin 54. The inner end of stud 52 hasva shoulder 55 which abuts theinner end of projection 5| to prevent displacement of stud 52 to theright as viewed in Figure 5. The outer end of the stud has a reducedthreaded end 56 about which a nut 51 is threaded against the outer endof projection 5|; nut 51 and shoulder 55 preclude axial displacement ofstud 52 with respect to projection 5|. Threaded end 56 of stud 52 hasthreaded therein the inner end of an elongated tubular element 58similar to element 3| shown in Figure 1. This element 58 is interiorlythreaded and threadably receives a screw 59 similar to screw 32 shown inFigure l. The outer end of screw 59 (Figure 3) is adapted to be securedto the Window sash as described with respect to screw 32 (Figure 1) toeffect opening and closing of the sash upon actuation of the operator.

Operator (Figure 3) is adapted to be secured to a base plate such asbase plate |5 (Figure 1) so that upon rotation of crank 6|] (Figure 4)flexible cable 41 turns to rotate element 58. As element 58 rotates,screw 59 (Figure 3) is extended from or drawn intol element 58 to swingthe window. As the window swings, however, elements 58 and 59 alsoswing, and accordingly cylindrical housing 59 rotates in its grooves 48'element 3| (Figure 1).

and 49 (Figure 4). This rotation is possible by reason of the flexiblenature of cable 41 which assumes various positions within housing 50(Figure 5) as the housing follows the swinging movement of element 58and screw 59.

Generally indicated at 6| in Figure 6 is another modication of ouroperator. This form includes a base 62 and a top 63, which with a pairof wall portions 64 and 65 (Figure '1) form an enclosure 66 (Figure 8)in which a cupshaped housing 61 is rotatably disposed. Preferably walls64 and 65 are integral with top 63 and are connected to bottom 62 as byscrews 68 or the like (Figure 8) which extend through bottom 62 intowalls 64 and 65. Top 63 has a recess 69 formed therein, and from thisrecess a boss 19 extends angularly and upwardly from enclosure 66. Boss10 journals a stud 1 I, the outer end or which is connected to the shankof a crank 12 as by a set screw 13. The inner end of stud 1| extendsinto enclosure 66 and carries a coaxial bevel gear 14 which is adaptedto rotate within the enclosure and within recess 69 upon rotation ofcrank 12.

The lower end of a stud 15 is disposed in bottom 62 and the stud extendsupwardly into enclosure 66 through the bottom of cup-shaped housing 61.Bevel gear 16 is mounted to rotate in enclosure 66 about stud 15 and isin mesh with gear 14. Housing 61 has an opening 11, the edges of whichfit into a groove 18 formed on the inner end of a tubular threadedelement 19 similar to l The inner end of element 19 (Figure 8) carries asmall bevel 80 which meshes with bevel 16 and accordingly is rotatedthereby. An arm 8| extends through bevel 89 and is rotatably connectedto element 19, its other end lying within enclosure 66 and beingpivotally mounted on the upper end of stud 15 between aV pair of washers82 and 83. Washers B2 and 83 and the inner end of arm 8| are held inassembled relation on the upper end of stud 15 by a screw 84 threadedinto the stud.

Threaded tube 19 (Figure 6) is adapted to threadably receive a screw(not shown) similar to screw 32 (Figure 1). Upon actuation of operator6| (Figure 6) tube 19 and its screw operate the window as hereinbeforedescribed with respect to tube and screw 3| and 32 respectively (Figure1). In operation of operator 6| (Figure 8) rotation of bevel 14 by crank12.drives bevel 16 which in turn operates bevel 80. This causes element19 not only to rotate, but also to pivot about the axis of stud 15, asthe window swings in one direction or another. As elementY 19 pivotsabout stud 15, housing 61 turns within enclosure 66. It will now appearthat the bevels in enclosure 66 comprise a differential which not onlyrotates element 19, but also permits swinging of this element as thewindow operates between the full and dotted line positions shown inFigure 6. As described above with respect to operator 2| (Figure 1)operator 6|, (Figure 6) is also adapted to be secured to a suitable baseplate such as plate I5 (Figure l).

Turning now to Figures 9, 10 and 11, wherein still another form of ouroperator is shown, a housing 85 (Figures 9 and 11) is suitably securedas by brackets 86 to a base 81, in turn secured to base plate I5.Housing^85 and base 81 form an enclosure 88 in one corner of which (asshown in Figures 9 and 10) isrotatably disposed a bracket generallyindicated at 89. Bracket includes an upper portion 9D which projectsthrough the top of housing 85 (Figure 10) and is hollow to receive theupper end of a stud or shaft 9| to the upper end of which is connected acrank 92. The lower end of shaft 9| is rotatably mounted in base 87 andis rotatable with respect bothto the base and to bracket 89. Upperportion 90V of'- bracket 89 receives a bevel gear 93 which-isv carriedby and secured to shaft 9| by a pin 94 or the like.

Bracket 89 also includes a portion 95 angularly disposed with respect tobracket portion 99' and this bracket portion 95 rotatablyv supports oneend 96a of a screw 96 disposed withinenclosure 88. End 96a of the screw'which lies within bracket 89 carries a bevel 9-1 which meshes with bevel93 so that rotation of bevel 93 imparts rotation not only tobevel 9T butalso toscrew 96. v

As noted above, bracket 89 is rotatable within enclosure B8 and thuswill turn about the -axis of shaft 9|. Similarly, screw 96 will swingabout the same axis. f Y

An interiorly threaded nut 99 is threaded en screw 96 and, as shown inFigure 11, is constrained against rotation -about the screw Vby reasonof its disposal between the bifurcations 99a and 99h of a bifurcatedlever 99. Nut 98 is also pivotally related to bifurcations99a Vand 9913by oppositely extending studs |99 'and ||l| which extend respectivelyinto suitable holes formed in bifurcations- 99al and 99h. FromA theabove, accordingly, it appears that rotation of screw 99 effects axialmovement of nut 98 with respect to the screw.

Lever 99 (Figures 9 and 1l) is fulcrumed by a pin |92, which extendsthrough the lever and through a block |93 secured to plate 89 in whichit is maintained against axial displacement in any suitable manner. Afriction slide shoe |95 (Figure 12) is secured to the outer end of lever99, and slides back and forth in a track |96 secured to sash bar 29 asthe window swings. Thus, movement of lever 99 operates the window.

Upon rotation of crank 92 (Figure l0) the meshing bevels 93 and 91rotate screw 99, causing movement axially thereof of nut 98. Assumingsuch rotation of screw 99 as will move nut 98 downwardly, as viewed inFigure 9, this movement of the nut moves lever 99 clockwise, i. e. in adirection to close the window. However, as the nut moves toward the freeend of screw 98, screw 96 is swung toward the lever fulcrurn |92 untilthe screw and lever reach their dotted line positions wherein the windowis completely closed. Reverse rotation of the various operating parts,of course, results in opening movement of the window. Furthermore, byreason of the relationship between nut 98 and screw 96, the window issecurely held not only in its open and closed positions, but also in anyintermediate position, as forces exerted on the window normal to itsplane are ineifective to cause rotation of screw 99.

Accordingly, it will be seen that we have provided a Casement windowoperator characterized by simplicity in design and efficiency inoperation, in addition to its ruggedness and neat apin combination, arhousing secured tosaid frame, said housing including a substantiallyhorizontal base portion andl a substantially -vertical web portion lyingin a plane parallel to the plane of la threaded element, meansoperatively connecting said Yelement to said member so as-'to rotateupon rotation of said crank,` a second threaded element threadablyassociated with said rst threaded element and constrained againstrotation with respect thereto, whereby upon rotation of said firstelement by said crank said second element is moved axially o f thefirstVand means for connecting said second element tothe window foroperation thereof.
